Abstract

PURPOSE: To provide a planted tree zone capable of introducing not only rain fallen on the planted tree zone but also rain fallen on roads into the planted tree zone, giving a sufficient amount of the water to a tree and simultaneously allowing excessive rain water to permeate into the ground to prevent the lowering of the underground water level and the flood damages to a city, and preventing the roots of the tree from spreading under the road to prevent the surface roughening of the road. CONSTITUTION: This planted tree zone comprises two faced buried side plates 2 whose upper ends are exposed on the ground, linking members 3 for incorporatively linking the side plates 2 on both the sides to each other, and earth and sand charged between the side plates on both the ends, and has flow-in holes for allowing rain water to flow in the planted tree zone at the upper ends of the side plates 2 exposed on the ground.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tree planting zone provided along a road or the like.

[0002]

2. Description of the Related Art FIG. 4 is a sectional view of a conventional tree planting zone.
In the figure, 11 is a curb, 12 is a sidewalk, 13 is a roadway,
14 is a tree. As shown in the figure, the conventional planting body has a curb 1 for planting a belt at the boundary between the roadway 13 and the sidewalk 12.
No. 1 was installed and the inside was used as a tree planting zone.

[0003]

Since the conventional tree planting zone has the curb blocks 11 for the tree planting zone on both sides as described above, the rainwater absorbed by the tree planting zone will be absorbed on the tree planting zone. Rainfall alone is not always enough for trees and sometimes they have to be watered. Since the rain on the road 13 and the sidewalk 12 is drained by a separate water distribution facility, the rainwater hardly penetrates into the ground, which causes a decrease in groundwater level and urban flood damage. In addition, the roots of trees may overhang the road and lift the soil on the road (particularly the sidewalk) to make the pavement uneven. The present invention solves such a problem and guides not only the rain falling on the planting zone but also the rain falling on the road to the planting zone, giving sufficient water to the trees and surplus rainwater. It penetrates inside to prevent lowering of groundwater level and urban flood damage, and also prevents roots of trees from protruding below the road to prevent the road from becoming uneven.

[0004]

SUMMARY OF THE INVENTION According to the present invention, two opposing side plate portions 2 having their upper end portions exposed and buried in the ground and the side plate portions 2 on both sides are connected to each other and integrated with each other. Side plate 2
The tree planting zone is characterized in that the inflow hole 4 is formed in the exposed portion above the ground at the upper end portion of the side plate portion 2 and is filled with earth and sand.

[0005]

Since the present invention has the above-mentioned structure, the rainwater that has fallen on the road flows into the planting zone from the inflow hole 4, giving sufficient moisture to the trees and surplus rainwater permeating into the ground.
Further, the side plate portion 2 prevents the roots of trees from protruding below the road and prevents the road from becoming uneven. Since the side plate parts 2 on both sides are integrated by the connecting part 3, it is possible to have sufficient strength against the pressure of the root of the tree, and the side plate part 2 and the connecting part 3 are made into blocks to plant the tree band block 1 By doing so, it can be easily installed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the drawings of the embodiments. 1 is a cross-sectional view of a tree planting zone according to the embodiment, FIG. 2 is a top view of the tree planting zone block 1, and FIG. 3 is AA in FIG.
It is a line sectional view. In the figure, 1 is a planting zone block, 2 is a side plate part, 3 is a connecting part, 4 is an inflow hole, 5 is a water pipe, 6 is a sidewalk,
7 is a roadway, 8 is a gutter, and 9 is a tree.

The tree planting zone shown in FIG. 1 is composed of a side plate portion 2, a connecting portion 3, an inflow hole 4, a water conduit 5 and earth and sand filled therein. The side plate part and the connecting part are made of concrete, as shown in FIG.
As shown in Fig. 3, the planting zone block 1 is factory-produced. The tree planting block 1 is composed of two facing side plate parts 2 and three connecting parts 3 for connecting and integrating the side plate parts 2.
Two inflow holes 4 are opened in the upper portion of each side plate portion 2, and a PVC resin water guide pipe 5 protruding downward is connected to the inside of the inflow hole 4.

As shown in FIG. 1, the planting zone block 1 is
The inflow hole 4 is exposed to the outside and buried in the ground, and the inside is filled with earth and sand to plant trees. A large number of planting zone blocks 1 are connected and buried according to the required length. The lower part of the planting zone is filled with sand with a relatively large particle size or a large amount of gravel mixed to improve the penetration of rainwater and to prevent clogging of the water conduit, and the upper part is filled with humus. Has been done.

Rainwater that has fallen on the sidewalk 6 and the road 7 is introduced from the inflow hole 4 through the water conduit 5 to the lower part of the tree planting zone. Providing the water conduit 5 eliminates the possibility that rainwater will overflow from the tree planting zone even in the case of heavy rainfall.

[0010]

INDUSTRIAL APPLICABILITY In the tree planting zone of the present invention, rainwater that has fallen on the road flows into the tree planting zone from the inflow hole, gives sufficient water to the trees, and surplus rainwater penetrates into the ground, so watering the trees is performed. There is almost no need to do so, and it contributes to lowering groundwater levels and preventing urban flood damage. Further, the side plate portion prevents the root of the tree from projecting below the road, and thus prevents the road from becoming uneven. Since the side plate parts on both sides are integrated by the connecting part,
It has sufficient strength against the pressure of the roots of trees,
Further, the side plate portion and the connecting portion can be formed into a block and can be easily installed. If a water conduit is installed, rainwater will be guided to the bottom of the planting zone, so there is no risk of rainwater overflowing from the planting zone even in the case of heavy rainfall.
